Inside-out burger with tomato-Worcestershire ketchup

Ingredients:

Hamburger

• 100 g chopped bacon
• 0.5 cup chopped red onion
• 3 tablespoons raw chorizo ​​sausage, casing removed
• 900 g of ground beef, 20% fat
• 200 g Swiss cheese, thinly sliced, about 8 slices
• 4 Kaiser rolls, cut in half and fried

Ketchup

• 3 tbsp. l. olive oil
• 1/4 cup diced red onion
• 8 plum tomatoes, peeled, seeded and cut into 0.5cm pieces.
• 1 tbsp chopped garlic
• 2 tablespoons Worcestershire sauce
• 1 tbsp. apple cider vinegar
• 2 tablespoons of sugar
• 0.5 tsp chopped dill
• A pinch of allspice
• A pinch of celery salt
• A pinch of mustard seeds

Preparation:

1. In a medium skillet over medium-high heat, fry the bacon and onion. The bacon should release its fat but not become crispy. Add the chorizo ​​and fry until cooked through. Then transfer the bacon and chorizo ​​mixture to paper towels and let cool.
2. Divide the ground beef into 8 equal portions. Roll into loose balls and form into 10 cm diameter patties. Layer 1 piece of cheese, 1/4 of the bacon mixture, and another piece of cheese in the center of each patty. Top with another patty, and gently press the edges of the 2 patties together. Repeat with the remaining patties to make a total of 4 large patties, each 10 cm in diameter and 4 cm thick.
3. Heat a medium frying pan over medium heat. Place 4 patties in the pan and cook for 3-4 minutes on each side. Then carefully flip and cook for another 3-4 minutes on the other side. Remove the pan from the heat, cover with a lid, and bake in the oven at 120°C for 10 minutes.
4. Remove the patties from the oven, place them on buns and serve with tomato-Worcestershire ketchup.
   
   This dish will be complemented by the bouquet of red Merlot wine.
